“We are going to call the chain with the most accumulated difficulty Bitcoin or BTC,” a blog post issued Monday reads.

“If the minority chain is the one with 1MB blocks we are going to call it BC1 and if the minority chain is the one with 2MB blocks we are going to call it BC2.”

The move is a firm commitment to support the SegWit2x chain if it gains majority consensus, while confusion could equally ensue if users additionally interact with a service calling a different chain ‘BTC.’

Calls to boycott Xapo

Reactions on social media to the decision focussed specifically on this point, users concluding the only way to avert chaos from miners switching between majority support would be to change which chain was ‘BTC.’

Other response were harsher, with well-known Twitter commentator WhalePanda calling for an outright boycott of Xapo.

Bitcoin holders meanwhile are still waiting for commitments from other major wallet providers. Coinbase has notably stayed silent on the issue, with only former engineer Charlie Lee offering insight into what will likely happen when the fork occurs on Nov. 18.
